SelectTranslate

SelectTranslate is a free browser extension that translates content as you go. It turns regular web pages into bilingual views, handles PDF documents, adds translated subtitles to YouTube and Netflix, reads images and comics, translates ePub ebooks, and even follows live Zoom, Teams, and Meet meetings. There's no need to copy text into a separate window; the translation appears right where you are.

Under the hood, SelectTranslate pulls from more than 20 AI translation models. The lineup includes DeepSeek, GPT, Gemini, Claude, Qwen, Kimi, DeepL, and a few options for local or open models. You can pick a model for a specific text or use best-choice mode, which decides which model gives the clearer result. The extension also includes direct input translation, select-to-translate, and hover translation, so quick lookups don't interrupt your reading flow. It supports translation between more than 100 languages.

The people who get the most out of SelectTranslate are those who regularly cross language boundaries: researchers reading papers in another language, students studying abroad, remote workers on international calls, and anyone who prefers original articles with translated support. Because it's a browser extension rather than a standalone app, it feels light and fits into an existing workflow.
